I was playing 7.5 ladies combo. I had been serving well all night, especially to the 4.0 opponent in the deuce court. Tight match. First set 5-7. Second set 6-6. In the second set tiebreak, I hit a doublefault. "That's weird," I thought. "No reason to change anything. I've been serving fine." I DF'ed again in the set tiebreak, but we won it. Then we had the 10-point match tiebreak. I DF twice more, which means I am now DF's on half of my service points. Somehow we still managed to get to 9-6. I stepped up to serve to the 3.5 player in the ad court. Whappo, into the net. Second serve, into the net. Now it's 9-7. I serve to the 4.0 player in the deuce court. Whappo, into the net. Second serve, hits ground before going into the net. 9-8. My partner received serve in the ad court, got it into play. Opponents missed a shot, we won, 10-8. I am used to my serve going in, even on break points, set points, match points. I can't chalk it up to being nervous, because I wasn't. OK, how on earth am I ever going to have confidence in my serve again? Is this how the service yips start? It's way too cold to go out and practice. I am not looking forward to my next match . . . .
